How to perform exercise

Grasp a couple of dumbbells holding them by your side at arm's length.

Stand with your torso straight and your legs spaced using a
shoulder width or narrower stance. The knees should be slightly bent.
This is your starting position.

Keeping the knees stationary, lower the dumbbells to over the top
of your feet by bending at the waist while keeping your back straight.
Keep moving forward as if you were going to pick something from the
floor until you feel a stretch on the hamstrings. Exhale as you perform
this movement

Start bringing your torso up straight again by extending your hips
and waist until you are back at the starting position. Inhale as you
perform this movement.

Repeat for the recommended amount of repetitions.

Caution: This is not an exercise that is recommended
for people with lower back problems. Also, it needs to be treated with
the utmost respect paying special attention not to round the back
forward as you move the torso down; the back should always be straight.
Finally, jerking motions or doing too much weight can injure your back.
